I know it happens; it's happened to me, and I have probably touched fewer
switches than you. Still, from what I can understand, it can be
prevented/minimized by the use of a grounded port.
"CAUTION: If you want to install the Switch using a Category 5E or
Category 6 cable, 3Com recommends that you briefly connect the cable
to a grounded port before you connect to the network equipment. If you
do not, the cable’s electrostatic discharge (ESD) may damage the Switch's
You can create a grounded port by connecting all wires at one end of a
UTP cable to an earth ground point, and the other end to a female RJ-45
connector located, for example, on a Switch rack or patch panel. The
RJ-45 connector is now a grounded port."
